On the morning of January 26, 2006 I drove my 2003 vw Passat at short distance (approx) 3 miles. As I arrived at my destination and pulled into a parking place the car died on me. There did not appear to be anything that precipitated the failure. I did not understand what happened but I soon began to smell smoke. I got out of the car, opened the hood and saw that there was a fire in the engine compartment. From the front of the car, facing the engine compartment, the fire was located toward the upper left-hand corner of the compartment near the front passenger side. The fire was fairly far along before the fire department arrived. Ultimately, the car was totaled by my insurance company. A police report was filed with the local police, a claim was filed with my insurance company and a complaint was filed with Volkswagen customer service. …
My 2003 vw Passat gl sedan sputtered, stalled and subsequently caught fire in the engine compartment around 6:30 pm, jan 26th, 2007, in holmdel nj, police report # 07-1914 holmdel police dept. The car has been maintained well by a local vw dealer since purchase and there has been no modifications made, nor any signs of trouble prior to the incident. The fire was very extensive and put out by holmdel nj fire dept and the car is totaled. The symptom just prior to stalling is consistent with ignition coil failure which was recalled by vw until 2002 model year, I.e., engine warning lights, sputtering, smokes under hood and though exhaust and final stall. The engine stall nearly caused collision due to the loss of steering boost and the fire was rapid and large. …
Vehicle oil pressure light alerted driver of low oil pressure. Driver brought vehicle to r&j auto on 1309-1365 barnum avenue in bridgeport, ct; driver purchased car from this business less than a year ago; driver was told that nothing was wrong with the car. A week later the same issue arose while on the highway. Driver was not speeding due to getting off of the ramp. Car began making a ticking noise. Driver brought car back to r&j a week later the car was deemed unfit to drive due to sludge, the oil pump being damaged and the engine malfunctioning. Dealer/mechanic informed me that the car was dangerous to drive and would not be worth fixing. I was forced to junk the car and leave the car with the business. I am afraid they will resell the car without completing the proper maintenance and repair to another innocent customer. This car is not fit to drive.

I have had my 2003 vw Passat a year now I have just noticed in the past week that it had a leak I thought it was from the window or sun roof I went to vacuum the car out on a nice day and seen that it still had very wet carpet and then noticed the carpet was a green color like it was coolant I then had my bf check it and it is. I run a daycare and use this car daily with my children we have been breathing in this coolant for weeks now and that probably explains my daughter saying she gets headaches when we drive the car. I have done some research and see it is a very common and recalled thing with the heater core and I had no idea I hope us breathing this in hasn't done any damage I have a one year old who has been in it this whole time as well.im very unpleased with this car.
Driver was on daily commute to work, stopped at an intersection. A loud bang was heard by the driver and when the driver exited the car to see what had happened, a bystander immediately yelled toward the driver to warn them that the car was on fire. Driver was able to make it out of car safely, with minor injuries incurred as a result of trying to put out the fire. The fire itself was limited to the engine compartment, however as a result the entire engine and engine compartment were destroyed and the car was considered a total loss by insurance. Since the defective component(s) and surrounding area involved in the defect were completely destroyed, there was no parts to repair or replace.
